Abstract
The utility model relates to a double-iron-notch and single-casting-house system for a blast furnace, comprising a blast furnace, slag skimming devices and a swinging sliding nozzle, wherein the blast furnace is provided with two auxiliary casting houses. The double-iron-notch and single-casting-house system provided by the utility model is characterized in that the two auxiliary casting houses are respectively arranged at the two sides of the blast furnace and are arranged in a straight line, the auxiliary casting houses and the blast furnace are arranged in parallel with the original casting house, and one tap hole is respectively arranged on the blast furnace along the direction of the two auxiliary casting houses; and the slag skimming device is arranged in each auxiliary casting house, the slag skimming devices are respectively connected to an iron runner and a slag runner, the tap holes are connected with the slag skimming devices by virtue of the iron runner and then are connected with the original casting house by virtue of the iron runner, the swinging sliding nozzle is arranged at the outlet of the iron runner, and molten iron is released into a molten iron tank by virtue of the swinging sliding nozzle. According to the double-iron-notch and single-casting-house system provided by the utility model, the auxiliary casting houses are added, and the two iron notches are arranged in an angle of 180 degrees, so that nonuniform corrosion in peripheral direction of a furnace cylinder can be reduced or avoided, and positive effects for stabilizing production of the blast furnace, saving energy, reducing consumption, improving operating quality of the blast furnace and prolonging service life of the blast furnace can be realized.
Description
Technical field
The utility model relates to the ironmaking technology field, specifically a kind of pair of iron mouth blast furnace list casting house system.
Background technology
Be used for the blast furnace of ironmaking, need to discharge molten iron by iron notch.Relatively large blast furnace generally need to arrange two above iron notchs, has the blast furnace of two iron notchs according to routine, and two casting houses generally can be set, and with two iron mouths respectively correspondence be arranged in two casting houses, make two iron mouths mutually be 180 ° of layouts.This decoration form is best, can guarantee that the blast furnace hearth circumferential direction corrodes evenly, is conducive to the carrying out that produces.
Because be subjected to the restriction of place, space and transport condition, the blast furnace that tends to have two iron notchs also arranges a casting house, and simultaneously two iron notchs are and are less than or equal to 90 ° of angles and arrange.For large blast furnace, if the side that two iron mouths are arranged simultaneously namely in casting house, it is inhomogeneous not only to cause easily the cupola well circumferential direction to corrode, and stable to blast furnace production, and energy-saving and cost-reducingly all consists of impact.
The utility model content
For the deficiency of prior art, a kind of pair of iron mouth blast furnace list casting house system is provided, by increasing auxiliary casting house, realize that two iron mouths are the scheme that 180 ° of angles are arranged, to improve the operation of blast furnace quality, prolong blast furnace campaign.
The technical scheme in the invention for solving the technical problem is: a kind of pair of iron mouth blast furnace list casting house system, comprise blast furnace, skimmer and swing slide mouth, described blast furnace is provided with two iron notchs, it is characterized in that, also be provided with two auxiliary casting houses, two auxiliary casting houses are arranged in the blast furnace both sides, linearly distribute, described auxiliary casting house and blast furnace together are arranged in juxtaposition with former casting house, are respectively equipped with an iron notch at described blast furnace along two auxiliary casting house directions; And in assisting casting house, be provided with skimmer, and described skimmer is connected respectively to iron runner and slag runner, and described iron notch is connected to former casting house through behind the skimmer by iron runner, and in the iron runner outlet swing slide mouth is installed.
The beneficial effects of the utility model are: by increasing auxiliary casting house, realize that two iron mouths are 180 ° of angles and arrange, it is inhomogeneous to alleviate or avoid the cupola well circumferential direction to corrode,, raising operation of blast furnace quality stable, energy-saving and cost-reducing to blast furnace production, and prolongation all can be played active effect blast furnace campaign.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: 1 blast furnace, 2 iron notchs, 2 ' iron notch, 3 skimmers, 3 ' skimmer, 4 swing the slide mouth, and 4 ' swings the slide mouth, 5 slag runners, 5 ' slag runner, 6 iron runners, 6 ' iron runner, 8 former casting houses, 7 auxiliary casting houses, 7 ' auxiliary casting house, 9 slag runners.
Embodiment
As shown in Figure 1,
A kind of pair of iron mouth blast furnace list casting house system comprises blast furnace, skimmer and swing slide mouth, and blast furnace is provided with two iron notchs, and two iron notch one the first from left right sides are symmetrical arranged about blast furnace.
Also be provided with two auxiliary casting houses, two auxiliary casting houses are arranged in the blast furnace both sides, and auxiliary casting house and blast furnace together are arranged in juxtaposition with former casting house, and auxiliary casting house and blast furnace linearly distribute.Be respectively equipped with an iron notch at blast furnace along two auxiliary casting house directions, iron notch passes through the outside transferring iron melt of iron runner, and is provided with skimmer in iron runner, is used for scum and separates.The position of skimmer is arranged in corresponding auxiliary casting house.
Skimmer is connected respectively to iron runner and slag runner, and this is the design of routine, and iron notch is connected to former casting house by iron runner again after connecting skimmer by iron runner, and exports installation swing slide mouth at iron runner, and by swinging the slide mouth molten iron is discharged in the iron ladle.
Specifically, it by blast furnace 1, iron notch 2, iron notch 2 ', skimmer 3, skimmer 3 ', swing slip mouth 4, swing and slip the compositions such as mouth 4 ', slag runner 5, slag runner 5 ', iron runner 6, iron runner 6 ', former casting house 8, auxiliary casting house 7, auxiliary casting house 7 ', and former shared slag runner 9.The auxiliary casting house 7 that increases newly and auxiliary casting house 7 ' be arranged symmetrically in respectively the both sides of blast furnace 1, and together arranged side by side with former casting house 8 in blast furnace 1.Iron notch 2, iron notch 2 ' are arranged in auxiliary casting house 7 and auxiliary casting house 7 ' direction; Skimmer 3, skimmer 3 ' are arranged in auxiliary casting house 7 and the auxiliary casting house 7 '; Swing slide mouth 4, swing slide mouth 4 ' still are retained in the former casting house 8; One end of slag runner 5, slag runner 5 ' is connected with skimmer 3, skimmer 3 ' respectively, and the other end is connected with former shared slag runner 9; Iron runner 6, iron runner 6 ' one end are connected with skimmer 3, skimmer 3 ' respectively, and the other end is connected with swing slide mouth 4, swing slide mouth 4 ' respectively.
The utility model is creationary to be 180 ° of layouts with two iron notchs and single casting house problem solves; no matter be overhauling reform blast furnace or newly-built blast furnace; be 180 ° of layouts as long as relate to two iron notchs, and only have a casting house to belong to this patent protection domain.
Except the described technical characterictic of specification sheets, be the known technology of those skilled in the art.
